What to Focus On

  • Einstein mass-energy relation: ΔE = (Δm)c²
  • Mass increase due to supplied energy: Δm = ΔE / c²
  • Rest-mass energy: E₀ = m₀c²

  • Pair production is conversion of energy into mass
  • Pair annihilation is conversion of mass into energy
  • Minimum gamma-photon energy for pair production is 1.02 MeV

  • Mass defect is the missing mass of a stable nucleus
  • Δm = Zmp + (A − Z)mn − mN
  • Binding energy is the energy needed to break a nucleus into free nucleons

Common Mistakes to Avoid

Mass-energy relation means mass and matter are the same thing.

1 kg of mass is equivalent to 9×10^16 J, so 1 kg can be converted into that much energy in ordinary situations.

Pair production can occur with any gamma ray, even if its energy is below 1.02 MeV.

Memory Tips

Einstein mass-energy relation

1 kg mass equivalent

Mass does not mean matter in the mass-energy relation

Mass increase due to added energy
